PEBISCOPE.

Specification of Letters Patent.

Patented June 30, 1914.

Applicati n1led` January 28, 1914.' Serial No. 814,929.

Be it known thatv I, JOHN HANsoN, a subject of the King of Great Britain, and a resident of Naas Harbor, in the Province of British Columbia' and Dominion of Cana-da, have invented a new and Improved Periscope, of which .the following is a full, clear, and exact description.r My invention relates to devices whereby thecourse of a boat can be.viewed from its lower deck, and wherefrom the course can be controlled.

Theobject of my invention is to provide a simple, strong and inexpensive periscope which formscalso, a ventilator and a skyc light and is adapted to carry a projecting lamp coacting with the periscope.

I obtain the above object by providing a rotatable turret having therein a pair of coacting, turnable, reflecting mirrors forming the periscope, said turret forming a ventilator, andalso having a lens at the top thereof forming the skylight, and a projectinglamp adapted'to engage the'turret above said lamp and coactin wlth the mirrors.

The invention consists ofthe `construction and combination of parts to be more fully described hereinafter and fully set forth in the claims.

Reference is to be had to the accompany- `ing drawings forming a part of this spec-ification, in which like characters indicate corresponding parts in all the views 4and in which:

Figure 1 is a vertical, axial "section through an embodiment of my invention; Fig. 2 shows ajdiferent form of projecting lamp; Fig. 3 sliows the vperscop'e positioned above the ilot house, that is, the turret being provi ed with an extension from'the main deck so as to pass through said floor;

Figs. 4 and 5 show the connecting means for the parts of the periscope'; Fi'g. 6 is a perspective view of the turret with its vbearing; and Fig. 7 is aperspective view showing the bottom of the turret.

Referring `to the drawings, 8 epresents i the main' deck of the boat where n is provided a tubular support 9 forming a stuifing-box for. the tubular memberlO. The tubular member 10 carries adjustably thereon a crown 11 having a ball race registerin'g'with a ball race providedin the member 12, which, with the support 9, forms the stulin -box. race o the crown 11 and the member 12 balls Positioned between the ball receiver a lens frame 19 forming a lightI inlet for the cross 18 and, therefore, the tubular member 10. -The said frame 19 is provided on its lateral surface with lteeth'20 similar to the teeth 15 and adapted to be engaged by teeth 21, similar to teeth 16, said teeth 21 being formed onau extension of a projecting lantern 22 and, therefore, the said lens frame 19 forms a support for the projecting lens. which projecting lens is intended to be used at night to illuminate the course -of the boat, so that the reflected light of said lamp can be received by the mirror 23 mounted to rotate in the cross 18, and to face the glass screen opening 24 of the cross 18.

The tubular member 10 extending below the deck 8 engages a guide 25 secured to the underside of the deck, and bearing against the edge of said support is a union 26 connecting a tubular extension 27 to the tubular member 10. In said tubular extension 2-7 a mirror 28 is mounted to rotate, said mir- 'ror being similar to the mirror 23 and facing the same, so as to lreflect the rays coming through the screen opening 24 to the mirror 23 into the opening 29 provided in said tubular extension. The trunnions of the mirrors 23 and 28 are rovided with arms 30, the free ends of which are interconnected by parallel rods 31, whereby by moving the lower mirror 28, the upper mirror 23 is moved correspondingly within the turret formed by the tubular members and the cross. The turret proper can be rotated on its ball bearings 13 by applying an effort to handles 32 provided on the tubular extension 27, whereby the course of the boat and the surroundings can be seen.

` The cross 18 at the end opposite. the glass screen opening 24 is provided with a mem- -ber 33 formin the 'ventilator for the turret,

so that while t e Opening 24 admit-s the rays to the mirrors, the opposite end of the cross admits air through the turret Vinto the engine room from where the course of the vessel is controlled by inspecting the said course through the opening. 29. Further- 1, is-produced by acetylene or gas, which is supplied through a flexible tube 34, whichwill not interfere with the rotation of theV i turret and, therefore, the lamp therewith. As shown in Fig. 2, the light used with the projecting lamp 22 is an electric lam in which case the wires leading t0 the amp and, fromthe source are connected to each other at a plug switch 35 formed in the cross 18.

'In Fig. 3 the turret proper is elongated by inserting an additional tubular member 36 between the cross 18 and the crown 11, in which case the cross 18 is not provided with the extension 17 but the extension 17'.' is mounted on the tubular member 36.

, Fig..6 shows the tubular member 10 when the cross and mirrors are removed, that is,

, when the periscope is not in use. The lamp 22 is so mounted on the cross 18 that its-longitudinal axis is in the same plane with the .I axis of the screen opening`2f1 Aof the cross, i. which opening faces the mirror 23, so that `when the turret is rotated, the light from the projecting lamp 22 will illuminate objects adapted to be reflected by the..mir ror 23.

" HavingI thus described my invention, I

claim as' new and desire to secure by Letters Patent: Y

' 1. In combination, a periscope with a pro"-l jecting lamp, said lamp being adapted to Amove with the periscope and illuminate the 40 field embraced by-said periscope.

2; In a periscope, a turret having a cross member at the top thereof; reliecti-ng'mir'- rors in -said turret, said cross memberv having an air and light admission through said 46 turret; and alight inlet to said mirrors.

`3. :In a periscope, a turret having a cross member at the top thereof; a bearing for said turreton which they same can be rotated; coacting reecting 'mirrors in saidv turret,'sai d cross having alli ht. inlet to Said mirrors, said cross having yalso a light inlet forming a skylight for the turret and an air y inlet forming a ventilatorfor the same.

4. In a periscope, a tubular member; a cross at the top of said member; means for removably connecting said cross to said tubular member; a bearing for said tubularl member whereon the same can bev rotated; aA mirror in said cross; a mirror in said tubular member; means connecting said mirrors whereby the same can` be operated in unison, said cross hav-ing a li ht inlet to the mirror therein, asecond lig t inlet in alinement with said tubular member forming a sky light therefor and an air inlet for ventilating said cross and tubular member.

In a periscope, a tubular member; a ball bearing for said member whereonthe same can be rotated; a crsspositioned at the top' of said tubular member; meansfor removably connecting said cross and said tubular member; a mirror rotatably mounted in said' cross.; a second mirror rotatably mounted in said member adjacent the bottom "u,

thereof; means connecting said mirrors whereby the same `can 'be moved in unison, the cross having' a screened light inlet for the mirror therein; an air inlet in alinexnent with said light inlet; a frame carrying a glass associated with saidcross in alinement 4with said tubular member and forming therefor a skylight; and a projectin lens removably associated with said lens rame, substantially as and for the purpose `set forth. i In testimony whereof I have signed my name to this specification in the' presence of two, subscribing witnesses.
